Bosch oven emits a strong burning smell or smoke during normal cooking (not first use)

Safety first: If you see heavy smoke or flames, turn off the oven and breaker immediately and keep the door closed. Use a fire extinguisher if necessary.

• Inspect cavity: Once cool, remove racks and check for heavy grease or spills on the bottom, walls, and elements. Clean with a Bosch-approved oven cleaner.
• Check elements: Look for areas where grease has dripped onto elements. Clean gently when cool.
• Monitor temperature: Use an oven thermometer to ensure the oven is not overheating beyond the setpoint. If it is, test the temperature sensor and control board.
• Inspect wiring: If the smell is electrical (sharp, acrid), disconnect power and inspect wiring and insulation for burning. Replace any damaged components.
